Thank you very much for reviewing beautifully. However, I have kept the conversation brief; it should have been extended further. I will try to do better next time.

At the same time, I have answered some of your questions along with your comments. 👇👇

The girl who was affected by SCID disease here was the chairman's daughter; she donated her heart to another girl, and that girl was Dr. Amina, meaning the director who has died. There were various research papers, old photographs, and documents related to SCID in the 12 lockers, and so many lockers were used for safety. Since the director had secretly established a laboratory in the basement without anyone's knowledge, no one noticed it, and laboratories generally exist in quiet environments for focus and concentration. The director, being like the chairman's daughter, did not need any permissions for this; his research was for the betterment of the country, and this is why his dead body was there for so long; only the senior surgeon knew because he was the one who committed this murder.
